ABEL PATCHE N, OF WESTFIELD, NEW YORK.

SOLUTION OF DICHLORIDE OF COPPER, dc, FOR TREATING ORES.

SPECIFICATION forming part of Letters Patent. No. 319,118, dated June 2,1885.

Application filed May 21, met (No model.)

To aZZ whom it may concern:

Be it known that I, ABEL Paronnn, a citi zen of the United States,residing at Westfield, in the county of Chautauqua and State of liewYork, now temporarily residing in Mexico, have invented certain new anduseful Improvements in Processes of Making Dichloride of Copper, ofwhich the following is a specification, reference being had therein tothe accolupanying drawings.

This invention relates to the process of male ing dichloride of copper,or a solution or a product for use in treating ores chemicallyforinstance, according to the process set forth in United States Patent No.170,535 granted to Henry H. Eames and myself jointly, November 30, 1875,or any other process in which a I chloride of copper is employed.

The invention consists in the method hereinafter set forth.

Referring to the drawings, Figure 1 is a cen tral vertical section ofthe apparatus. Fig. 2 is a detail hereinafter described. Fig. 3 is aplan of the cover of the apparatus.

Like letters indicate like parts in all the fignres.

A represents the body of the apparatus, which consists of an ordinarycylinder of suitable metalas boiler-plateopen at both ends, to which issecured in any suitable manneras by rivets or boltsa bottom, B, which inthis instance is flat, but which may be semispherical, or of any othersuitable outline, if desired.

0 represents a top, which in this instance is a casting of any desirablecontour, having a flange, 0, which is perforated for the passagetherethrough of bolts or rivets 6*. At the upper portion of the top issecured in any suit able manner an angular hoop or band, D, having aprojecting flange flush with the upper edge of the body and faced off toagree with the under surface of the top, so that an air and steamtightjoint is made between them when bound together by the bolts.

The band I) may be secured to the body by bolts or rivets, which, likethose securing the bottom to the body, terminate at their inner endsflush with the surface of the body.

The top 0 is provided with an opening, 0 through whichthe chemicalsemployed in the process are introduced into the apparatus. A

cover, E, is provided for the opening and overhangs the same, and isslotted, as at E, for the reception of the bolts E, which are pivoted atE to ribs E, formed as a part of the cap, so that by loosening the nutsof the bolts E they may be swung outwardly on their pivots to free thecover for removal, as well as to serve as means for firmly binding thecover in place, so as to securely close the opening against the escapeof steam therefrom.

F represents any ordinary steanrsupply pipe, which passes through thetop and reaches nearly to the bottom of the apparatus or vessel. Theentire inner surface of the body and bottom of the vessel or apparatusis coated with any suitable material which will resist the action of thechemicals used in the process. I have found by experience as best, andrepresent in this instance, a lining, G, of lignum-vitac, and the pipeFjs also coated or covered and protected by the same means, as may alsobe the top.

H represents the dischargeplu g, preferably made of lignum-vitze, firmlydriven into the opening in the wall of the body portion of the vessel,near its bottom. A faucet of ordinary construction, preferably made oflignum-vitie, may be inserted in the bore of the bushing H, and serve asmeans for withdrawing the contents of the vessel at will.- In thisinstance the plug is tapered, so as to form a tight fit in the holeformed in the body of the vessel, and is provided with an annularshoulder, H, upon which is mounted a binding-plate or washer, I, whichis secured by bolts or rivets to the outer wall of the vessel, so thatthe plug or bushing is firmly held in place and against removal fromsteam or other pressure within the vessel.

In making dichloride of copper with this apparatus, or any other whichis adapted to the process herein described, I place within it in anydesired or necessary quantities or proportions metallic copper, adesired salt as chloride of sodium-and a solution of sulphate ofcopper-that is to say, water and sulphate of copper. I then close thehead tightly, and also the discharge-opening or any faucet therein, asdescribed, and heat the mixture by means of steam introduced through theICO pipe F, and by reason of the confinement of the mixture within theapparatus and the entire closeness of the-same I also simultaneouslysubject the mixture to a pressure exerted by the steam.

By the employment of the lining, for which the copper has no affinity,the apparatus is rendered capable of long-continued use, and successivewithdrawals from and renewals of the mixture may be made, so that aconstant supply is provided.

I do not limit my invention to any proportionate quantity of theingredients, nor to any particular strength of any solution of sulphateof copper, nor to any particular degree of pressure exerted upon themixture at the time of heating the same, except, the process being in aclosed vessel, the pressure would evidently be more than that of theexternal atmosphere.

No claim is herein made for the apparatus, as that properly forms thesubject-matter of a separate application.

I have herein designated the product of my process as dichloride ofcopper, but what- ABEL PATOHEN.
